1. Datura ferox L. (S-USA and C-Am.) – A rather rare and ephemeral alien. First recorded in 1938 on waste land in the valley of river Vesdre (Verviers, Renoupré), probably as a wool alien. Subsequently observed on several occasions in this area until 1957. In the 1940’s and 1950’s sometimes seen on dumps, especially around Charleroi and Antwerpen, probably as a birdseed alien. From the 1970’s onwards much increasing, usually as a grain alien (unloading quays, near granaries, on grain dumps, manured fields, roadverges,…). Since 1993 seen most years in port areas in Flanders, probably most often introduced with soybeans (Verloove & Vandenberghe 1994).
